I'd say that in the 80s most game concepts were invented, but many suffered from the technical limitations of the time. In the 90s, most of these limitations were gradually lifted. The high point is probably different from game category to game category.
For instance Pac-Man, Tetris, or Galaga are still good fun today. Ditto Super Mario Bros. Flight Simulator II? Sorcery? not so much. There are plenty of 3D games from the early 90s perfectly fun to play, and some IMO like "Thief" haven't been bested in gameplay.
